Abstract: An electroimpedance tomograph is provided with a plurality of electrodes (1), which can be placed on the body of a patient and are connected to a control and evaluating unit (20) via a selector switch (60). The control and evaluating unit (20) cooperates with the selector switch (60) such that two electrodes each are supplied with alternating current from an AC power source (22). The detected analog voltage signals of the other electrodes are sent into the control and evaluating unit (20) via a measuring amplifier (62) and AD converter (64) and are processed there in order to reconstruct the impedance distribution of the body in the plane of the electrodes therefrom. A symmetrical AC power source (22) is used to reduce common-mode signals. To make it possible to suppress errors due to common-mode signals, provisions are made for the control and evaluating unit (20) to be set up for making available an additional common-mode signal at an output during an adjusting mode of operation and to send it to the body via common-mode signal electrodes (4, 90) that can be placed on the body. The control and evaluating unit (20) is prepared, furthermore, to adjust the measuring amplifier (62) according to value and phase for each electrode pair connected by the selector switch (60) such that the common-mode signal at the output of the measuring amplifier (62) is minimized, and the adjusted parameters are stored for each electrode pair.

Abstract: The invention is directed to a measuring apparatus for detecting gases with the aid of an electrochemical sensor with a diffusion barrier being disposed ahead of the sensor. The measuring apparatus is improved in such a manner that the sensor is adaptable with respect to its sensitivity to different measuring ranges during operation without external intervention. The speed of response of the sensor is also increased. Diffusion openings in the diffusion barrier are closable with a valve arrangement associated with the valve openings. The valve arrangement is connected via a valve drive unit to a measurement value comparator for changing the operating position of the particular valve to be actuated.

Abstract: A device for the analysis of the qualitative, optionally also the quantitative composition of gases, uses measuring light of known spectral composition that can pass through the gas to be analyzed and the gas can be caused to interact. A detector arrangement is present, which can detect light originating from the sites of the interaction between the measuring light and the gas to be analyzed. At least one refractive-diffractive optical element is provided, which is transparent over its entire surface and contributes to a wavelength-dependent imaging of the light to be detected onto the detector arrangement in a transmitting manner. The refractive-diffractive optical element is arranged in the ray path between the area in which the interaction between the gas to be analyzed and the measuring light takes place and the detector arrangement.

Abstract: The invention relates to an apparatus and a method for improved correction of drift in an infrared measuring instrument. The measurement signal furnished by a thermal detector is split into a direct voltage component and an alternating voltage component. By means of calibration curves (24, 27), a calculated comparison variable T DC , korr 900 is formed from a measured, averaged concentration value c AC1 900 . The correction value ΔT for the drift correction is obtained from the difference between the corresponding measured size of the direct voltage component T DC 900 and the comparison variable T DC , korr 900 .
